IMPROVEMENT IN THE MODES QF LUBRICATING AXLES.

The Schedule referred to in these Letters Patent and making part: of thesame.

To all whom. it may concern 7,

Be it known that 1, JAMES IVES, of Mount Garmel, in the county of NewHaven and State of Connecticut, have invented a new and improved Mode ofLubricating Axles; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawing making part of this specification, in which--Figure 1 is a diametrical section through an axlebox having myimprovement applied to it.

Figure 2 is'a diametrical section through the box taken at right anglesto the sectional plane of fig. 1-.

Figure 4 is an end view of the axle-box.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to axle-boxes for the wheels of vehicles, and hasfor its object improving an axlebox by utilizing one of its ears as aconduit for the supply of oil to the axle, as will be hereinafterexplained.

The following description will enable others skilled in the art tounderstand my invention.

In the accompanying drawing-- A represents an axle-box, which, with thefollowing exceptions, may be made in the usual well-known manner.

One of the ears to is extended to the end of the box so as to form anarrow enlargement, c, which is continuouswith said ear, and throughwhich a hole, I), is formed that is inclined, as shown in fig. 1.

This hole or conduit 7) leads from the outer terminus of theear-extension, a, down to a fan-shaped depression,-d, which is made intothe inner surface of the box A, at or near the middle of its length.

The hole or conduit b is screw-tapped for a short distance to receive ascrew-threaded portion, which is formed on a stem, 0.

The reduced portion or stem 0' of the screw 0 is intended to serve as aplunger, and should extend to the inner extremity of the conduit 1), asshown in fig. 1.

The screw and its stem can be removed or inserted by means of a commonscrew-driver.

It will be seen, from the above description, that the inclined oroblique conduit affords an excellent means for supplying oil to an axlewithout removing the wheel therefrom; also, that the expanded chamber (1will receive the oil and spread it upon the surface of the axle inabroad h'hn; also, that the screw and its stem or plunger serve as ameans for stopping theud of the conduit 7), while the stem serves as aplunger or piston for compelling-oil put into the conduit b to flow intochamber cl, and also for preventing the conduit from becoming clogged,or clearing the same if clogged.

1 do not claim an oil-chamber which is formed in the manner shown in therejected applicationof E. Burts, November, 1853, and of R. Platt, April30, 1859. Neither do I claim an incline passage closed by a screw-plug;but

\Vhat I do claim as my invention, and desire to secure by LettersPatent, is-

1. The ordinary axle-skein or box improved without changing the form ofthe axle or materially'changing the construction of the skein or box, byconstructing one of the cars or lugs a with an extension, 0', and.perforating said ear obliquely so as To form the conduit b, andterminating said conduit intheform of a flaring or expanded chamber,d,wh'ich chamberis formed within the inner circumference of theaxle-box, all in the manner substantially as described and shown.

2. The combination of the combined plug and piston, partlyscrew-threadcd, with the inclined conduit b and the expanded chamber at,all in the manner described andsh'own.
